[SPHR] There is Only One King

Synclone Resonator
Dark Fiend / Tuner / Effect
LV1 100/100
You can only Special Summon “Synclone Resonator” with its (1) effect once per turn. (1) If there is a Synchro Monster on the field, you can Special Summon this card (from your hand). (2) If this card is sent from the field to the Graveyard: You can target 1 “Resonator” monster in your Graveyard, except “Synclone Resonator”; add it to your hand.

Chain Resonator
Light Fiend / Tuner / Effect
LV1 100/100
(1) When this card is Normal Summoned while there is a Synchro Monster on the field: You can Special Summon 1 “Resonator” monster from your Deck, except “Chain Resonator”.

*Red Daemon is included in the names of all monsters the TCG calls “Red Dragon Archfiend”, but it’s entirely possible they might expand this theme to beyond that and have monsters like “Red Daemon Golem” or “Red Daemon Resonator”, so I’m leaving it be for now. But you can think of it as saying “Red Dragon Archfiend” monster right now.
